Do You Need a Permit for a Porta Potty in St. Charles County?
Most porta potties in St. Charles County need no permit at all. The exceptions are units in the street, units in a city park and units at a permitted public event. Here is how to tell which one you are, and who to ask.
Do I need a permit for a porta potty on my own property?
A porta potty on your own driveway, lawn or job site usually needs no city permit in St. Peters or other St. Charles County cities. The unit is temporary and sits on private land. Subdivision HOA or trustee rules may still limit how long a unit can stay visible, so check those for rentals longer than a week.
Practical tip: a spot beside the garage or at the back corner of the driveway keeps the unit off the sidewalk and out of the neighbors' view.
When does a porta potty in the street need approval?
A porta potty placed in a city street, on a sidewalk or in the public right-of-way may need approval from the city. In St. Peters, the Engineering department handles right-of-way permits. Keep units on private property whenever you can, because street placement also blocks plows, mail and parking.

What about block parties and events in St. Peters parks?
Block parties in St. Peters need a permit at least 2 weeks ahead, and parades need at least 4 weeks. Events held only in city parks are approved through Parks, Recreation and Arts. Large public events may also need insurance and a music festival or liquor license, which the city asks for up to 60 days ahead.
See the city's block party and parade permit page. If the park or permit office gives you a site map, text it to us and units go exactly where it shows.
Do job sites need a permit for a porta potty?
A porta potty on a private job site rarely needs its own permit; check with your building inspector if unsure. On a job site, the rule that matters is OSHA 29 CFR 1926.51. It requires 1 toilet for up to 20 workers, then 1 seat and 1 urinal per 40 workers.
